Study Endpoints
Death was the primary endpoint for the study. The secondary
endpoints were hospitalizations, therapy-related complications, correction
of anemia, and effects on nutritional status (as determined on
the basis of normalized protein equivalent of total nitrogen appearance
[nPNA] measurements and serum albumin, prealbumin, and transferrin
concentrations). Primary and secondary outcome events
(deaths, hospitalizations, and clinical events) were counted from the
time of randomization, whereas clinical and laboratory features were
assessed at scheduled intervals after randomization for the control
group and after stabilization of the dialysis prescription for the intervention
group.
